so with grbl v.9 or v1.1 in which i use the v1.1, pins 11 and 12 are being swapped to access the hardware PWM on D11 for variable spindle PWM output. But i'm using the CNC shield V3, that means that i ...

I needed a tacho/RPM display for a CNC spindle. I decided to use an Arduino Micro and OLED display with a reflective LED/Photo transistor as a sensor. Since powering up, a clock can display the total ...

An open source, embedded, high performance g-code-parser and CNC milling controller written in optimized C that will run on a straight Arduino - JimmyNXT/Ben_CNC_grbl ...

[Reza Naima] has been using an Arduino as the center of his CNC setup for quite some time now. It handles three stepper motors, limiting switches, e-stop, and spindle control. The sketch he’s ...

Initially, they put an Arduino inside the control box of the CNC and it fit nicely, but it turned out the Arduino’s CPU would restart every time the spindle spun up – apparently, EMC would ...

Universal (ish) Arduino grbl opto-coupler interface also works with logic-level pwm In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to ...

After a time with a multimeter and scope, the othewise-undocumented Cronos board for home-build cnc machines has revealed some of its secrets. Overall, it seems like a proper grown-up design with a ...

An interesting Arduino project has been published to the Instructables website showing how an Arduino CNC shield and controller has been used to create an awesome 3 axis Arduino CNC plotter. The ...

The Arduino PCB Ink Plotter CNC Machine is a DIY project that features a arduino running GRBL CNC firmware. In this project, it uses a marker that is suitable for plotting or marking the PCB for board ...

Arduino or electronic enthusiasts searching for a new project to keep them busy this weekend may be interested in the awesome Arduino controlled CNC foam cutting machine, constructed from a ...
